I posed this question on Twitter and you guys were kind enough to respond (@JoarGarrosh). The Best in Bags feature routinely suggests switching to the Kil'jaeden trinket while a number of other sources (IcyVeins for example) seem to suggest that several of my other legendaries are significantly better than that trinket. It may be that my other trinkets are pretty lousy, but wanted to see if you guys could help me understand. Thanks!
